Description

Technical Field

[0001] This utility model relates to the field of laser accessory technology, specifically to an intelligent control system for preventing sludge runoff in a biochemical tank decanter. Background Technology

[0002] Phase II C-TECH tanks #3 and #4 are each equipped with two independent decanters. Each decanter is controlled and its skimming speed is adjusted by a separate frequency converter, and each decanter is controlled by a control system. When the system needs to skim, the control system controls the two decanters to skim downward at a given speed (frequency) to complete the entire skimming process.

[0003] Because the mechanical, installation, and electrical parameters of the two decanters may not be completely identical, when the control system decanters (outlet weirs) descend at the same speed (frequency), the horizontal height of the outlet weirs may not be the same. The decanter with the lower height has a deeper draft and a larger decanting load, resulting in an imbalance in the decanting load (decanting flow rate) and causing instability in the water flow. The decanter with the larger load has a higher outflow velocity, which may disturb the settling of deep sludge. When the draft exceeds a certain amount, the load on the decanter will exceed its rated load, directly affecting the stability of the decanter's mechanical structure. Therefore, in the later stages of decanting, the decanter may sink, stirring up sludge from the bottom of the tank and discharging it, affecting the quality of the effluent and even damaging the mechanical structure of the decanter.

[0006] Furthermore, the center of the sliding gear is also connected to the balance box.

[0022] like Figure 1 As shown, a smart control system for preventing sludge runoff in a biological tank decanter includes all the contents of Embodiment 1. In addition, the gear module includes a fixed gear A4, a fixed gear B5, a fixed gear C6, and a sliding gear 3. The two ends of the top horizontal support of the fixed frame 7 are rotatably connected to the fixed gear A4 and the fixed gear C6, respectively. The fixed gear B5 is rotatably arranged next to the fixed gear A4, and the sliding gear 3 is arranged diagonally below the fixed gear B5. The traction chain 8 passes through the fixed gear B5, the sliding gear 3, the fixed gear A4, and the fixed gear C6 in sequence and then connects to the decanter weir 9.

[0023] Optionally, the center of the sliding gear 3 is also connected to the balance box 2.

[0024] The technical effect achieved by the above embodiment is that the gear module composed of fixed gear A4, fixed gear B5, fixed gear C6 and sliding gear 3 enhances the stability of the traction chain 8 transmission.

[0025] Example 3

[0026] like Figure 1As shown, a biological tank decanter anti-sludge intelligent control system includes all the contents of Example 2. In addition, the balance box 2 is composed of multiple counterweights that can be detachably connected together.

[0031] Example 4

[0032] like Figure 1 As shown, a smart control system for preventing sludge runoff in a biological tank decanter includes all the contents of Example 3. In addition, a display screen is provided on the control cabinet 1.

[0033] The technical effect achieved by the above embodiments is that by setting up a display screen, it is convenient to observe relevant parameters.

[0034] Example 5

[0035] like Figure 1 As shown, a biological tank decanter anti-sludge intelligent control system includes all the contents of Example 4. Except that the fixed gear A4, fixed gear B5, fixed gear C6 and sliding gear 3 have the same number of teeth and the same nominal diameter.

[0036] The technical effect achieved by the above embodiments is that interchangeable installation of each gear is realized by having the same number of teeth and the same nominal diameter.

[0037] During use, the above-mentioned device monitors the real-time liquid level, the set liquid level for skimming, and the skimming time. The algorithm program precisely controls the speed (frequency) of the decanter and rationally distributes the rate of the decanter in each skimming stage to achieve a balanced load on the decanter.

[0038] To synchronize the skimming height, a horizontal height measurement is added to the two decanters in each biological treatment tank. The skimming speed of the two decanters is then controlled by a program to synchronize their skimming heights. A steel wire is installed on the weir of each decanter; as the decanter moves up and down, it moves the steel wire up and down as well. The length from the detection position to the decanter weir (denoted as H1 and H2) is calculated by detecting the angle through which the gears rotate.

[0039] The speed adjustment values ​​of the two decanters are given by the data algorithm based on the measured values ​​of H1 and H2, and the speed (frequency) of the inverters of the two decanters is controlled by the program. By monitoring the real-time liquid level of the C-TECH tank and the horizontal height of the decanters, the draft of the decanters is intelligently judged and controlled to increase the operational stability of the decanters.

[0040] When the measured value of a decanter suddenly increases (detecting that the gear rotation angle is too large), the control program can intelligently adjust the speed (frequency) of the decanter through the algorithm to precisely control the draft at different time periods and different liquid levels, so as to keep the two decanters in dynamic balance.
